list the "inquiries"
that can be made, the type(s) of object appropriate
to each, an explanatory version of each, and
the answer or type of answer returned.
<BR>
				<BR>
			<LI>Inquiries that start with "is" are true/false queries,
returning 1 (one) for "yes" and 0 (zero) for "no."
Such queries can be reversed, however, by inserting "not" after
the initial "is"&#58;
An "is not" query also returns 1 (one) for "yes" and 0 (zero)
for "no."
For example, if the subject of the inquiry is a scalar field,
"is scalar" returns 1 (one) and "is not scalar"
returns 0 (zero).
<BR>
				<BR>
			<LI>Any "is" query about a group whose members contain different
types of objects will return 0 (zero) unless all members have the
characteristic specified in the query.
For example, if a group is composed of two fields, one scalar and one
vector, the answer to the question "is scalar"
will be 0 (zero).
<BR>
				<BR>
			<LI>Any inquiry that returns a scalar integer value can be made to
return a value that is "1" higher or lower than that
value.
For example, "is array + 1" will return 2 (instead of 1) or
1 (instead of 0).
<BR>
				<BR>
				<LI>Capitalization of an inquiry is optional and its words may be
separated or run together.

					<br>
				<li><A HREF="refgu129.htm">Scale</A> transformations can generate unwanted distortions in objects such as <A HREF="refgu163.htm#HDRTUBE">Tube</A> or <A HREF="refgu122.htm#HDRRIBBON">Ribbon</A>.
